This whole thing has been confused by people using imprecise language. You expect that from journalists. But as he says, the 2012 rules were written by 2012 delegates. Likewise, the 2016 rules will be written by 2016 delegates. It may be that they look at the rules from the last convention as a template, but the fact is those rules are not in effect. There are no 2016 rules until they are adopted by the 2016 delegates. None of them carry forward automatically. There is no reason to think that any 2012 rule must apply in 2016 unless it's some normal and uncontroversial one. But that 2012 rule wasn't normal and was very controversial. It would only be in effect in 2016 if the convention once again specifically adopted it.
I am voting for Trump no matter what happens. Down ticket may or may not get my vote. Senator and Rep. Including my PA State House/Senate representatives. My GOP State Rep is useless. She inherited her position from her dead husband.I have met with her several times and she’s a hack. Jury is still out on the new GOP State Senator.
